HIGH SENSITIVE HALL-EFFECT SWITCH INTEGRATED CIRCUITS
These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications and high sensitivity, designed to operate continuously over extended temperatures to +150° C, and are more stable with both temperature and supply voltage changes. The unipolar switching characteristic makes these devices ideal for use with a simple bar or rod magnet.
Each device includes a voltage regulator for operation with supply voltages of 4.5 to 24 volts, reverse battery protection diode, quadratic Hall-voltage generator, temperature compensation circuitry, small-signal amplifier, Schmitt trigger, and an open-collector output to sink up to 25 mA. with suitable output pull up, they can be used with bipolar or CMOS logic circuits.
Features
Wide Supply Voltage Range
Fast Response Time
Wide Frequency And Temperature Range
Long Operating Life
Small Size, Convenient Installing
Output Compatible with All Digital Logic families
Typical Application
Contactless Switch. Position Control
Speed Measurement. Revolution Detection
Isolation Measurement. Brushless DC Motor
Automotive Ignitor
